一、WCF 简单介绍 |
Windows Communication Foundation(WCF)是由微软发展的一组数据通信的应用程序开发接口,是一套通讯接口。现在比较流行的SOA就可以通过WCF实现。他的功能如果非要用一个词来形容恐怕只能用“强大”,“完美”来形容。融合了remoting和webservices的强大功能,还推出了WCF配置的小工具,更加方便入手和进阶。 |
WCF 体系结构
|
二、今天想说的 |
1、Wcf经常需要添加新功能,需要发布新功能与修改配置文件 |
2、需要配置的信息很有特点(基本就是service,endpoint) |
3、配置多了,真的很烦,而且一不小心要是写错了就,糟糕了 |
进入主题啦,我们要说的是WCF自承载 |
三、WCF自承载 |
1、简单实现
1 ServiceHost host = new ServiceHost(typeof(Service1));
2 WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
3 host.AddServiceEndpoint(iType, nb, "http://127.0.0.1:8888/IService1");
4 host.Open();
这样就可以简单实现自承载了,现实中除了Http我们还经常用到Http
|
1 //添加支持TCP协议服务
2 private static void AddTcpServer(Type type, Type iType)
3 {
4 ServiceHost host = new ServiceHost(type);
5 NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
6 host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
7 OpenServer(host, type.Name + "Tcp服务");
8 }
9 //添加支持HTTP协议服务
10 private static void AddHttpServer(Type type, Type iType)
11 {
12 ServiceHost host = new ServiceHost(type);
13 WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
14 host.AddServiceEndpoint(iType, nb, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
15 OpenServer(host, type.Name + "Http服务");
16 }
|
2、平常用较常用的有可以通过防火墙的HTTP协议,和效率很高的TCP |
1 private static void AddServer(Type type, Type iType)
2 {
3 ServiceHost host = new ServiceHost(type);
4 NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
5 host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
6 host.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + " Http服务启动中" + "\r\n"); };
7 host.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + " Http服务已经启动" + "\r\n"); };
8
9 host.Open();
10 ServiceHost host1 = new ServiceHost(type);
11 WSHttpBinding nb1 = new WSHttpBinding(SecurityMode.None);
12 host1.AddServiceEndpoint(iType, nb1, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
13 host1.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + " Http服务启动中" + "\r\n"); };
14 host1.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + " Http服务已经启动" + "\r\n"); };
15 host1.Open();
16 }
这样已经强大了,传入服务和协定的Type,就可以实现服务在Http和Tcp上的承载了。当有一天我们需要msmq,当有一天我们想把服务运行情况的记录到数据库中,当...。通常需求是多变的,程序员要多给自己留点后路

3、后路 |
1 private static void AddServer(Type type, Type iType, bool useTcpHost, bool useHttpHost)
2 {
3 if (useTcpHost)
4 AddTcpServer(type, iType);
5
6 if (useHttpHost)
7 AddHttpServer(type, iType);
8 }
9 //添加支持TCP协议服务
10 private static void AddTcpServer(Type type, Type iType)
11 {
12 ServiceHost host = new ServiceHost(type);
13 NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
14 host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
15 OpenServer(host, type.Name + "Tcp服务");
16 }
17 //添加支持TCP协议服务
18 private static void AddHttpServer(Type type, Type iType)
19 {
20 ServiceHost host = new ServiceHost(type);
21 WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
22 host.AddServiceEndpoint(iType, nb, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
23 OpenServer(host, type.Name + "Http服务");
24 }
25
26 private static void OpenServer(ServiceHost host, string name)
27 {
28 try
29 {
30 host.Opening += delegate { ShowMessage(name + "启动中"); };
31 host.Opened += delegate { ShowMessage(name + "已经启动"); };
32
33 host.Open();
34 }
35 catch (Exception ex)
36 {
37 ShowMessage(host.ToString() + ex.Message);
38 }
39 }
40
41 private static void ShowMessage(string outMessage)
42 {
43 Console.WriteLine(DateTime.Now.ToString() + " " + outMessage + "\r\n");
44 }
第一眼相同的功能代码多多了。是不是很麻烦呢?要是你觉得是,那我承认我太失败了,这样之前说的问题就不用担心了,很简单就解决了。当时新的服务总是有,总是要我改代码,重新发布也麻烦啊。下面说不改代码的办法
|
4、不改代码的办法 |
1 static void Main(string[] args)
2 {
3 Setup();
4 Console.ReadLine();
5 }
6
7 private static void Setup()
8 {
9 string docPath = path + "\\Assembly.xml";
10 if (File.Exists(docPath))
11 {
12 XDocument xdoc = XDocument.Load(docPath);
13 foreach (XElement element in xdoc.Root.Element("BLLFiles").Elements())
14 {
15 LoadType(element.Attribute("FileName").Value);
16 }
17 }
18 }
19
20 private static void LoadType(string bllPath)
21 {
22 if (!File.Exists(path + "\\" + bllPath + ".dll"))
23 return;
24
25 Assembly bllAssembly = Assembly.LoadFile(path + "\\" + bllPath + ".dll");
26
27 Type[] types = bllAssembly.GetTypes();
28
29 foreach (Type type in types)
30 {
31 Type t1 = bllAssembly.GetType(bllPath + ".I" + type.Name);
32 if (type == null || t1 == null)
33 continue;
34 AddServer(type, t1, true, true);
35 }
36 }
1 Assembly.xml文件
2 <?xml version="1.0" encoding="UTF-8"?>
3 <AssemblyInfos>
4 <BLLFiles>
5 <BLLFile FileName="WcfService"/>
6 </BLLFiles>
7 </AssemblyInfos>
承认你丫的事情多,我用一个X妹儿没你要加载的Dll文件记录下。
然后反射去你所有的类。然后自动加载所有有协定的类。以后有新的服务在其他dll中,我加行BLLFil,哈哈哈,在此笑过。。。。
